If I could choose Brooklyn Decker as an option i'd want a Sandman van!

Back ontopic, just imagine that Sandman continued into WB, and that WB was updated into WD or WE or WF or whatever. By mid 1988 only just over 3 years after the end of WB we would have seen an injected 5 litre and 4L60 in a proper Holden. Probably a BW diff and rear discs too. Ford did it with the XG and XH so Holden could have done it too. Only downside would have been enduring that awful 3.0L Nissan engine and dodgy auto for a few years, plus a carbied ULP V8.
